IMPROVEMENT IN PULVERIZING DlSK-HARROWS.

Specification forming part of Letters Patent No. 214,189, da-tcdllpril8, 1879; application filed January 16, 187i).

To all whom it may concern:

' Be it known that I, RICHARD D. Neuron,

of New Sharon, in the county of Monmouth and State of New Jersey, haveinvented a new and useful Improvement in Pulverizing Diskllarrows, ofwhich the following is a specifi: cation.

Figure 1 is a top view of the burrow, partly in section, to show theconstruction. Fig. 2 is a side view of the same, partly in section,through the line m m, Fig")- Fig. 3 is a side view of the same, partlyin section, through the line 3 3 Fig. 1. Fig. 4 is a cross section ofthe same, taken through the line zz Fig. L Fig. 5 is a detail view ofthe slotted bu on.

Similar letters of reference indicate correspumling parts. v

The object of this invention is to improve the construction of thepulverizing disk-bar.- row in such a way that it may be more easily heldand controlled, and at the same time may be more durable and effective.Y

The invention consists in a double beating, combined with a bar securedat the rear end by two bolts and pivoted to the lower end of .ahand-lever, and in the combination of aeani and slotted button with aflattened-holdingbar, all as hereinafter described. Y

A represents the tongue to which thedmft is applied.

To the lower side of the rear end of the tongue A is attached across-bar, B, the outer ends of which are slot-ted to receive the boltsby which the bars 0 are secured to them. The forward ends of the bars Gare boltedto'The opposite sides of the tongue A, and'their rear ends arebolted to the bearings I), in which the shafts E revolve, a bushing,F,beingplaeed upon the said shafts within the bearings D to receive thewear.

Upon the shafts E; between the ends of the bearings I) and the disks G,are laced washers H, to lessen the friction an I prevent-the said disksfrom being worn 'bythe said ends.

of the bearings."

The inner ends or; the shafts E are pivoted to a bearing,I,withballand-soiflretjoints, so

am the some. E may be adjusted in line, or at an angle with each other,as may be desired.

The double bearing I is held in place by a bar, J, the rear end of whichis securedto it by two bolts, K, which pass through the said bearhig andare ibrmed upon or are attached to the said bar J.

The forward end of the homing-bar J is pivoted to the lower endot alever, L, which .ispivoted to the tongue A. The leverL is held in anyposition intowhich it may be adjusted by aprojection attached to it, andwhich engages with the notched edge of a plate at tachedto the tongue.

The holdinepbar J is made flat vertically, and passes through a slot inthe button M, which is bolted to the crossbar ll at the rear end ofthetongue A.

The two bolts K cause the bar J to hold 'the bearing 1 firnil and hornit securely in place. The slotted button M holds the bar J from turnhigor twisting, and thus causes the barrow to work more satisfzwtorily.

I Njs a cam-button, which is placedupon the bolt that secures theslotted button M, andis clamped against the said button bythenutvf -thesaid bolt.

- By this construction, by adjusting the cans button N the rise of theholding-bar J and of the midclie part of the burrow may belimited to anydesired point.

Having thus described my invention, Iclahn as new and desire to securebyLetters Patent-e 1.
